Abstract
A sawhorse frame is provided for use with a separate work-supporting top member that may be disposable. The frame is made with the paired legs at each end hinged together near their tops, and with pincer-like clamping jaws formed near the hinge points so that the work-supporting top member is very forcefully clamped in place. Force for this clamping is derived from the force with which the feet of the sawhorse are pressed against the floor, acting through a large mechanical advantage that arises from the foot-to-hinge distance's greatly exceeding the clamping-jaw-to-hinge distance. When the sawhorse frame is not in use, the same hinge arrangement facilitates folding the bottoms of the legs together to a more compact configuration for storage. Cross members that connect together the paired legs at the remote ends of the sawhorse are dimensioned and disposed to avoid their touching the work-supporting top member, so that the latter may serve even though it be a warped or otherwise irregular piece of lumber or other stock.
